The main object of my invention is to proonly contacted by the parts 7t,"e andd, so't' hat vide a new andimproved glass-cutting tool, a very small it'riction results,whenthe glass which is simple and durable in construction cutter is "moved over the glass plate k. and adapted to be easily manipulated.

One of the advantages of my glass" cutter By referring first to Figs. 1 and 2 it will is itssmall weight and a further advantage 5' be seen that a designates a graduated blade, is its ease of manipulation.

Adjacent head'slidably fitted together, said head being to the right or free end of the blade at is aadapted to eng agecthe edgeof a glass plate 0 body 03 and slidably arranged on theblade tobe cut, an extension atone end of'the blade a is a body 6. Whenthe device isused the continuing one edge thereof and adapted to blade is laid on a glass plate, resting upon be engagedby a glass cutter to be moved with the projections e and d, and the glass cutter the blade, a projection at the end of the blade is held against the extension 0 and the blade at one side surface thereof and adjacent said and cutter are moved together to cause the extension, said projection beingadapted to cutter to score the surface of the glass in the engage with the surface of the glassplate as usual manner. l r the blade'and cutter aremoved together.

Likewise slidably arranged on the blade 7 2. In alglass cutting tool, a blade anda a is asliding head This sliding head head slidably fittedtogether, said head being is adapted to be fixed in any desired posi adapted to engage the edge of a glass plate 5 The sliding head is formed onits right extension at one'e nd of the blade, continuing side semicircularly and provided with a one edge thereof'andadapted to be engaged notch Z. A pin or screw 11' fiXed inthe notch by a glasscutter to be movedwith the blade, serves asan axis fora roller h of hard ruba projection at the endof the blade at one together. 7

sion, said body and projection being adapted each to engage with the surface of the glass plate as the blade and cutter are moved 3. In a glass cutting tool, a blade, two

bodies associated therewith, one comprising a head in which the blade has sliding connection, means carried by the .headgforengaging the edge of a glass plate to be cut, the

other body comprising a rest adapted to engage upon the surface of the glass plate, and an extension at one end of the blade continuing one edge thereof and adapted to be engaged by aglass cutter to be moved with the blade.

a In testimony that I claim the foregoing as u my invention, I have signed my name.
